Patent CA-2000543-A1 (CA)
Inventor: BULLARA LEO A
IPC: A61N1/05
Filed: 1989-10-12
Abstract: A circumneural electrode assembly having a pair of spaced-apart and oppositely directed helical portions which can be opened by an insertion tool to fit the assembly over a peripheral or cranial nerve. One or more conductive electrodes on the inner surfaces of the helical portions intimately contact the nerve surface to deliver electrical stimulating signals, or alternatively, to block nerve conduction or to sense evoked potentials. The surgically implanted assembly is stable in position on the nerve, and is installed with a minimum of nerve manipulation and possible resulting trauma. The assembly preserves the advantages of previously disclosed spiral electrodes, while greatly simplifying installation, particularly in a nerve which is deeply recessed in overlying muscle or arteries.

Title: Directional solidification of metal matrix composites
Inventor: AGHAJANIAN MICHAEL K
IPC: C22C1/10
Filed: 1989-10-13
Abstract: A metal matrix composite is formed by contacting a molten matrix alloy with a permeable mass of filler material or preform in the presence of an infiltrating atmosphere.      Under these conditions, the molten matrix alloy will spontaneously infiltrate the permeable mass of filler material or preform under normal atmospheric pressures.      Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step, the matrix metal which has infiltrated the permeable mass of filler material or preform is directionally solidified.      This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.

Abstract: Abstract of the Disclosure A machine  for sanding flat  surfaces on workpieces is disclosed.   The workpiece to be sanded  is attached to a platen  on the  frame so that the  workpiece surface  to be sanded faces upwardly.  A motor rotatably drives an abrasive sanding   disc   about  a predetermined   axis  which   is perpendicular to  the flat workpiece surface.

Filed: 1990-02-28
Abstract: ABSTRACT OF THE DISCLOSURE          A self-routing switching system connected between input highways and output highways, includes conversion modules, doubled SRM networks, output modules, and first and second selectors.  Normally, one of the SRM networks is connected between the conversion modules and output modules through the first and second modules.  When a request to switch the active network to the other SRM network, the first and second selectors switch connections to the conversion modules and output modules so that the other SRM network is connected between the conversion modules and output modules.  Before actually switching the connections, it is determined whether or not all cells have been discharged from the active SRM network.

Title: Stacking packaging machine
IPC: B65B11/20
Filed: 1990-03-22
Abstract: Abstract A stacking packaging machine and 8 process for stacking and packaging resilient  workpieces.   The workpieces  are  usually  rolled paper products. The machine is comprised of an input conveyor, an elevator, cams,  workpiece  holders,  a packaging  film feeder and an output conveyor. A first group of workpieces is placed upon the elevator by the input conveyor and the elevator is lowered.  The workpiece holders are brought into place.  A second group of workpieces are fed into the holders and held above the first group.  The elevator begins to rise and the second group of workpieces are released. The stacked workpieces rise on the elevator toward the output conveyor.  Packaging film is fed over the stacked workpieces.  The film drapes over  the workpieces as they rise preventing any workpieces  from falling off the stack.  The workpieces enter the output conveyor and are moved to final processing.  The timing of the whole sequence is controlled by the cams.

Abstract: An apparatus for attaching bottom stops of a generally H-shaped cross section to a slide fastener chain. According to a preferred embodiment, a pair of stringer tapes of one of successive spaced element-free space sections are spread apart by spreading member. The top and bottom faces of the center base of the bottom stop are clamped resiliently by clamping members until attaching of the bottom stop to the fastener chain is finished and the clamping members move vertically for placing the bottom stop between the stringer tapes of the space section. The spread pair of stringer tapes ara then drawn near to come toward each other by drawing member until the beaded edges of the space section can be threaded respectively through spaces formed between the pair of gripping legs of the bottom stop. Then the fastener chain is transported so that the bottom stop is located to be contacted with the space section-side face of the terminal element of the row of coupling elements. Finally, the gripping legs of the bottom stop is crimped with a punch and a die for attaching the bottom stop to the fastener chain. In the present invention, since clamping operation is carried out so as not to interfere with crimping operation the bottom stop can be attached to the slide fastener chain surely and precisely.

Title: Electrical circuits
Inventor: MASOM RONALD A
IPC: H03K5/1252
Filed: 1990-08-14
Abstract: ABSTRACT OF THE DISCLOSURE         The effect of spurious spikes in an electrical circuit, such as, for example, caused by the passage of incandescent particles within the field of view of a pyrometer, can be reduced by a series arrangement of capacitor and resistor at the output of the circuit. The time constant produced by the capacitor and resistor is selected to give a shallow shape to the output so that the effect of spikes is reduced.  This also, however, affects the ability of the circuit to respond rapidly to normal changes in the input.         In the present invention, a second series arrangement of capacitor and resistor is connected to the first via a diode that isolates the second series arrangement from the first for short duration input pulses but connects them for longer duration input pulses so that a steeper slope can be achieved at the output.

Abstract: Shifting apparatus for use in a transfer press having moving die bolsters.   The  shifting apparatus  includes transfer rail sets that are located on the bolster and on the fixed bed that are interconnected during the normal transfer of the work pieces between dies.  Transfer fingers are carried by both transfer rail sets that serve to engage the work pieces  and move the work pieces  through the positions of the transfer press.   Transfer finger shift apparatus extends between the two rail sets and includes a shaft carrying a shift base member which has  transfer fingers connected thereto.  An elevating device is provided on the fixed bed to raise the transfer fingers sufficiently to pass over the top of the transfer fingers located on the bolster.  When it is desired to move the transfer fingers from the fixed bed to the bolster, the transfer rails are moved in the direction of the bolster moving the transfer fingers along the shaft and onto the bolster.  A lock is provided which attaches the transfer fingers to the bolster and the rails are moved toward the fixed bed.  The rails are separated and the bolster is moved to a remote location away from the press for replacement of the dies and related transfer fingers.

Title: Rollback inner cover
Inventor: MURPHY KATHERINE A
IPC: H01M12/06
Filed: 1991-02-28
Abstract: A cover for a galvanic cell having a reverse curved peripheral edge and a substantially centrally disposed upstanding wall bounding an aperture. A sealing member is positioned below the cover and has a tubular hub which projects through the aperture in the cover and a skirt that electrically insulates the edge of the cover. An electrically conductive fastener is positioned in the tubular hub on the sealing member which tends to cause the edge of the tubular hub to roll or "mushroom" when the electrically conductive fastener is peeved or clinched in place. The rolled tubular hub tightly locks the fastener and the cover together while the edge of the cover presses against the inner wall of the container holding the components of the galvanic cell. The pressure tends to slightly bow the cover enabling it to stay in a tightly sealed condition under both physical and thermal stress. A galvanic cell incorporating the cover is also disclosed.
